Dynamic autonomous resource allocation and channel access in cellular System Uplink

A method, comprising:

• forming collective high and low values from interference measurements performed by a plurality of local devices;
• calculating and deciding access for the plurality of local devices;
• and
• controlling the access of the plurality of local devices based on the calculating and deciding,
• wherein a probability of the access is computed without using a nominal power level obtained by downlink signaling, and wherein the probability of the access is used in the deciding the access.

An apparatus, comprising:

• at least one memory including computer program code;
• and
• at least one processor,
• wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to
• measure interference levels on uplink resources of a victim cell,
• calculate a probability of accessing channels of the uplink resources of the victim cell using the interference levels measured by the apparatus, wherein calculating the probability of accessing channels comprises defining a suitable transmission power, and a highest value and a lowest value,
• access a channel for which the probability of accessing has been calculated, when the probability meets a predetermined condition.
